I have a problem with a Gantt chart. The horizontal axis represents a date interval and in the vertical axis there are some project names. If the date interval for a project is just one day, you can only see a thin highlighted marker on the grid line, which is very ugly (see screenshot). I wanted to let a day be represented between two gridlines. To achieve this, the labels from the horizontal axis needed to be underneath the gaps and not under the grid line. How can I do this?
